I thought the game was a nice balance between a warcraft game (gather resources and build) and your traditional turret defense game, I also liked having the hero and lvl up system, the only thing I would suggest is maybe is the option to buy more carts and a skill selection for customizing your hero as he gained levels.
BTW after you get about 15 turrets or so you can get 2-5 of the rocket turret(this is for the later levels when they have super armored units) you can just sit back and save money, at the end any unspent cash is added to your points.
super easy, cool theme. This strategy worked on every level get 4-5 of the cheapest turret max upgrade then get the electro turrets about 3 and then go back and forth between shotgun and electro.
3.5 seconds, 5/5 game very cool concept and game play and I love the idea of custumizing your genome. By the way you can beat the game repeatedly to get the best DNA I have 8x "Jack" +2 all stats each.
